This fixes [BUGID #232], requiring root privileges to run these scripts and giving an error prompt when that requirement is not met. The tunctl uid fallback code has also been removed, as we can rely on the specific version of tunctl run from the native sysroot. Signed-off-by: Scott Garman <scott.a.garman@intel.com>
